Hi,
Why don't you use micros() to calculate G_Dt ?
It would be better if that value is more accurate don't you think ?

People who has RC1 running on their quads, you can post general feedback on
this issue.
If you find bug or what ever on RC1, please post new issue for each bug that
you have found. That way we can track better those

What is the expected output? What do you see instead?
Nothing happens when logger switch is put in "dump log" position. This is
because the logger switch should be defined as SW2. It is currently defined as
SW1.
Please provide any additional information below.
Changing "SW1_pin" to "SW2_pin" in the following two lines fixes the problem.
1: pinMode(SW1_pin,INPUT); //Switch SW1 (pin PG0)
2: while (digitalRead(SW1_pin)==0)

Checkup and find a reason why YAW is reversed on some quads. Motor arming is
correct way (tho down, rudder full right) but when flying right rudder rotates
quad to left (CCW).
Check YAW signatures, rotating quad by hand on floor to CCW makes it rotating
even more to CCW and not to CW like it should.

What steps will reproduce the problem?
1. put arducopter on the ground
2. increase throttle a little
3. one or two engines will start rotating but one or two will not
What is the expected output? What do you see instead?
When the throttle is above a certain minimum, all engines should be spinning.
engines should not be allowed to completely stop.
it can also cause problems when landing as one engine may stop just before
landing causing a nose-dive.
Please use labels and text to provide additional information.

What is the expected output? What do you see instead?
There are some integer overflow problems int the protocol. Some of these
changes are recommendations to change the protocol while others are simply
corrections so that the .def file matches the APM_STANDARD documentation on the
Ardupilot mega wiki. These are my suggestions but I am open for discussion.
1. changed goundSpeed to match doc
2. yaw and ground course should be uint16 to allow 0 to 360 *100
3. time of week should be uint32 to allow for timeOfWeek in milliseconds
4. pressure altitude should be allowed to be negative since this is possible
when the pressure rises after calibration
5. airspeed should be allowed to be negative for cases when a vaccuum could
form on the airspeed sensor (such as helicopters flying backwards
6. added renormSqrtCount, renormBlowupCount, gpsFixCount since they were
listed in doc

I've created a library that is cross-platform and interfaces to the APM_BinComm
class. It utilizes boost asio for serial communication, boost posix time to
emulate the millis function, and cmake as the build system.
This "library" consists of one wrapper class for Stream, a boost AsyncSerial
class from Terraneo Fedrico (much thanks), and an implementation of strlcpy.h.
This is all LGPL compatible so I would encourage you to add it to the BinComm
library. This should really help all of us writing GCS software for
arducopter/pilot. Contained in the library zip file that I have attached is
the BinComm library with my suggested patch.

People mount the magnetometer in different ways. Most common methods are:
1. components up, pins facing backwards
2. components down, pins facing fowards (mounted directly on OilPan)
We should allow a method in the code (or a setting in the EEPROM) to handle the
different mounting possibilities.
Two methods suggested by Doug:
a) enhance the AP_Math library to handle rotations, then define a set of rotations and in the ArduCopter code, rotate the results from the magnetometer before combining into the DCM
b) add an orientation setting into the APM_Compass (or AP_Compass) and have the library rotate results before passing back to arduCopter code.

As in general definitions to avoid future hassle, let's agree asap what values
we should get out from encoder. Eg Rudder full right = 2000, Ail right = 2000
or 1000, Ele up = 2000 or 1000....

mode.

Control equation of arducopter for stable mode is like this:
control_XXXX = D . ( P . error ( t0 ) + I . Sum ( error ( t ) ) - Omega )
This is making PID adjustment difficult. It will be easier to adjust If we
write the equation like
control_XXXX = P . error ( t0 ) + I . Sum ( error ( t ) ) - D . Omega
My proposal is to change
control_XXXX = STABLE_MODE_KP_RATE_PITCH*err_XXXX;
to
control_XXXX = stable_XXXX - STABLE_MODE_KP_RATE_XXXX*ToDeg(Omeg[1]);

Right now on the ardupilot-mega side we are using the XPlane protocol for HIL.
But it seems much easier to just define a new message for the binary protocol
under the radio section that outputs the current servo positions. The servo
positions can then be fed to the dynamics. The rest of the xplane protocol
packets aren't required for HIL. On the arducopter side this would require
updating the protocal.def file and regenerating the protocol.h file with awk
for APM_BinComm.

The standard Arduino Serial library blocks until all characters are sent which
can cause the main loop to slow down especially if we're using a slow xbee
connection.
We should replace the standard Serial library with an equivalent library that

What steps will reproduce the problem?
1. Test board 1 - No issues with BMP085. Library calls in both the demo
program and APM firmware return good pressure values.
2. Test board 2 - BMP085 demo program gives good data but AMP firmware gets
pressure value of 0 returned from library call
3. Test board 3 - gets pressure value of 0 returned from library call in both
demo program and APM firmware
Jason and I noticed this problem today. We have not been able to pin the
problem down after examining it for an hour or so. It is very odd that it
works on one board, works on 1 board with some software but not other, and
doesn't work on the third.
